AC DC Converters, Offline Switchers Procurement Notes

Verify the specific suffix 'SQ' against official Texas Instruments documentation to confirm automotive qualification status and temperature grade requirements. Ensure the 'NOPB' designation aligns with lead-free manufacturing standards required by your assembly process. Cross-reference the WQFN-28 package dimensions with your PCB footprint library to guarantee mechanical compatibility during procurement.

AC DC Converters, Offline Switchers Selection Notes

Select this component when designing phase-shifted full-bridge converters requiring wide frequency adjustability. It is suitable for applications demanding robust thermal performance in elevated ambient conditions. Consider its 2 A drive capability for direct gate driving of external MOSFETs without additional buffer stages. Evaluate the 100% duty cycle limit against system transient response needs.

AC DC Converters, Offline Switchers Part Context

This part belongs to the LM5046 series of switching controllers from Texas Instruments. It is categorized under PMIC - Power Management ICs. The device complements other TI solutions like the LM5045 by offering specialized phase-shifted control rather than standard full-bridge or half-bridge topologies.
